I have been thinking of installing two 

 feed pipes, each 1%-inch, to feed a 2- 

 inch main, which would extend along 

 the roof; then down, returning under 

 a bench; back again to the far end, 

 across the end and back to the heater 

 under the other bench. The house is 

 10x14 and nine feet high to the 

 ridge. The walls, aside from the glass, 

 are constructed of four thicknesses of 

 lumber and paper. I am enclosing a 

 sketch of the house and piping. Tou 

 will note that the 2-inch pipe, after 

 running twice to the farther end of the 

 house and back, is reduced to two 1%- 

 inch returns at the heater. Is that the 

 best way to arrange the piping! I 

 wish to run the house at 65 degrees 

 when the outside temperature is 30 de- 

 grees below zero. There are ninety 

 square feet of glass.

The sketch shows four feet of glass 

 in the north slope of the roof and six 

 feet in the south slope. We infer that 

 there are about two feet of glass in the 

 south wall, but the amount, if any, in 

 the north wall is not indicated. 



For maintaining a temperature of 65 

 degrees when the outside temperature 

 is 30 degrees below zero, we would 

 suggest the use of one square foot of 

 radiation to two square feet of glass. 

 The letter states that there are ninety 

 square feet of glass in the house, but 

 according to the sketch there are 140 

 square feet of glass in the roof alone, 

 besides something like 132 square feet 

 in the two ends and south wall. Even 

 if there is no glass in the north wall, 

 we would have to figure the wooden 

 walls as fully equivalent to twenty-eight 

 square feet of glass, making a total of 

 300 square feet. For this we advise the 

 use of 150 square feet of radiation. 



Instead of carrying the piping four 

 times the length of the house and twice 

 across the end, we would use the two 

 1%-inch flow pipes as feed pipes for the 

 coils. Carry one of these flow pipes 

 upon each of the side wall plates and, 

 at the farther end of the house, con- 

 nect them with the coils, of which there 

 should be one under each of the side 

 benches, with eight 1%-inch pipes in 

 each coil. 



If there were only ninety square feet 

 of glass in the house, it would be possi- 

 ble to heat it with forty-five square 

 feet of radiation and this would be fur-
